I just played this in my first year undergrad jury with few problems. Oddly enough, I found the third movement of Ravel's Sonatine to be trickier than this. I think this piece sounds harder than it is.
The biggest challenge is holding everything together and getting the bass to growl. The passagework itself is very forgiving, since it's a very chromatic blur. Playing it at the marked 104 bpm is insane though, and I don't even think it sounds great at that tempo anyway. I played it around 96, pushing the tempo in places it's really needed.
It's also extremely repetitive with regards to the technique required. Sure, the passagework changes a lot, but once you get the tangled figuration figured out it's really not THAT bad. The Liszt you're playing seems more difficult.
Regardless, this really is a matter of what your technique favours. I can play quick passagework with few problems, but very jumpy chordal stuff is quite killer. You should be able to judge its difficulty messing around with it for a few days. Even if it might be too hard for the moment, you're likely not far off from being able to handle it.
